The spaced apart annular edges defining a gap no wider than the diameter of the cable being wrapped about the hub of the shortener.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to cable or line shorteners and more particularly to methods of constructing that shortener apparatus to permit the ready height adjustment of a ceiling suspended sign, and is co-pending with commonly assigned U.S. patent application Ser. No. 09/______ entitled “Hanging Cable Shortener Apparatus” (Rose-10), which is incorporated herein by reference in its entirety.

[0003] 2. Prior Art

[0004] Retail commercial establishments often display signs and banners suspended from a ceiling by one or more cables or lines. Often the length of these cables or lines need to be changed depending upon the size of the sign or the height of the ceiling. Replacing these cables or lines, cutting them or crimping loops onto the end can be an expensive and inaccurate way to accomplish such height adjustment.

[0005] A number of devices are in the field, which permit such cable length adjustment. These mechanisms, however, appear unduly complicated and hence more expensive and undesirable for large use thereof and more likely to be utilized incorrectly.

[0006] U.S. Pat. No. 5,870,845 to Ruderman, et al shows a banner display system which includes a plurality of gears. This makes the system somewhat expensive. U.S. Pat. No. 4,434,570 to Roos shows an advertising support which also utilizes gearing arrangement for adjusting the height of a sign or a banner. A cord stowage apparatus is shown in U.S. Pat. No. 4,802,638 to Burger et al. This cord stowage apparatus comprises a spool having a pair of flexible cup shape members which are arranged to pinch a cable wound around there between. This is a somewhat sophisticated device which would not provide a strong griping tension for supporting a sign nor be able to support any appreciable weight due to the flexible nature of the material. U.S. Pat. No. 1,272,272 to Kell shows a globe shaped cord adjuster which utilizes a wrapping of a cord around a spherical body for adjusting the length of that cord. This apparatus is overly complex, highly visible, and would result in kinking of the cable. It is also infinitely adjustable meaning that signs may not hang level. U.S. Pat. No. 980,319 to Milam shows a take-up for flexible suspensories utilizing a pair of annular flanges separated by a hub and a pin arrangement for shortening a cable. The cable is held in place around a core by frictional engagement with the parallel sides of the hub. Any release of pressure in the cables (such as the sign being bumped or otherwise being lifted upwardly) will result in the adjuster popping off the cable, allowing the sign to drop several inches. Also, pins as described are not adequate to lock cable in place and any complication with added complexity of pins, it becomes easy for signs to be hung non-level due to small adjustment increments. U.S. Pat. No. 815,422 to Gregory shows and adjustable suspension device utilizing a set of pulleys.

[0007] The prior art thus discloses a cable and line shortening apparatus which, however, is somewhat complicated to manufacture, thus expensive to produce, and may not satisfactorily grip the cable in a readily sustainable manner.

[0008] It is an object of the present invention to provide a cable shortener apparatus which overcomes the disadvantages of the prior art.

[0009] It is a further object of the present invention to provide a cable shortener apparatus which is inexpensive to manufacture and easy to assemble.

[0010] It is yet a still further object of the present invention to provide a cable shortener apparatus which is readily useable and re-adjustable with minimum complexity thereto.

[0011] It is still a further object of the present invention to provide a cable shortener which is minimally obtrusive and which can be readily moved out of the line of sight, particularly after it has been applied to a cable.

[0012] It is still another object of the present invention to provide a cable shortener apparatus which does not kink or otherwise mar the cable as by wrapping about sharp bends.

[0013] It is another object of the present invention to provide an apparatus which is virtually impossible to hang a sign in a non-level manner.

[0014] It is still another object of the present invention to provide a cable apparatus which when put in place, will not release except by a conscious effort.

BRIEF SUMMARY OF THE INVENTION

[0015] The present invention comprises a sign cable shortener apparatus for hanging signs and displays from an overhead support such as a ceiling, beam or the like. A cable having an upper end would be attached to a ceiling or overhead support, and the lower end of the cable would be attached to the sign to be supported from that ceiling or overhead support. One or more wraps of cable would be taken (or untaken) around the cable shortener as descibed herein below, to shorten or lengthen that cable as necessary.

[0016] The cable shortener apparatus of the present invention thus comprises a rigid annular hub having a pair of ends. A rigid annularly-shaped curvilinear flange is disposed at each end of the hub. Each curvilinear flange extends radially outwardly from the respective ends of the hub. Each curvilinear flange has a peripheral lip which is also disposed radially outwardly of the hub. The curvilinear flanges are spaced apart from one another on the hub to define a cable wrap-space between the flanges and about the hub.

[0017] The rigid peripheral lip of a curvilinear flange on one end of the hub is spaced apart a certain distance from the rigid peripheral lip on the curvilinear flange on the other end of the hub. The certain spaced-apart distance of the peripheral lips is preferably greater than the diameter of the cable (line, drawn plastic filament or wire or the like) being utilized to support a sign from the overhead support or ceiling. The certain spaced-apart distance of the peripheral lips is critically less than the two cable diameters, so as to prevent unintended wrapping (or more likely unwrapping) of the cable past itself in the gap, that is, the certain spaced-apart distance between the opposed peripheral lips of the flanges. It would thus take a certain manual effort to squeezably move/slide one cable past itself in the gap between the peripheral lips of the flanges to unwrap and thus adjust the length of that cable during its support of a sign. This effort would be easily accomplished by a store employee where such a sign were hung.

[0018] The cable shortener apparatus may be readily adjusted, location wise on the extended cable itself merely by sliding the shortener apparatus one way or the other on that cable or line, the cable or line being slid about the hub of the shortener apparatus as the shortener apparatus is being moved, with no winding of the cable/line squeezingly past or over itself between the peripheral lips being necessary.

[0019] One preferred embodiment of the construction of the shortener apparatus comprises a first annular ring and second annular ring, each identical to one another. The first (and second) annular ring comprises an annular housing having a curved outermost wall from a circular outermost edge to a generally circular innermost edge.

[0020] Each ring has an axis of rotation which is perpendicular to the plane of the annular housing. Each ring has a pair of arcuate locking flanges extending axially away from the inner edge of the curved side of the annular housing. Each arcuate locking flange is preferably an arcuate segment of about ninety degrees. Each arcuate locking segment is spaced apart from one another on the inner edge by about ninety degrees. Each arcuate locking flange has an axial length equal to the axial length of the opposed ring into which it will mate.

[0021] Each annular ring has arcuate hub flange extending an axial distance away from the curved wall of the annular ring. Each annular hub flange comprises an arcuate segment of about ninety degrees, and has an outermost peripheral surface which defines an (outer) hub or drum for winding receipt of a cable thereabout. Each arcuate hub flange on each ring is disposed between adjacent arcuate locking flanges. Each adjacent locking flange has a radially outermost peripheral surface which is dimensioned and spaced so as to be received radially inwardly of each arcuate hub flange.

[0022] In the assembly of a sign cable shortener apparatus, a first ring is mated with a second ring, each of those rings being out of phase with one another preferably by ninety degrees, so as to permit the radially outer peripheral surface of the arcuate locking flange to slide radially inwardly of the arcuate hub flange of the other ring of the sign cable shortener apparatus.

[0023] When the two rings are mated together, the inner curvilinear peripheral wall of each ring and the circumferentially adjacent surfaces of the arcuate hub flanges defines a cable wrap area in which a sign hanging cable may be wrapped circumferentially therearound. The outermost peripheral lips of each ring are rigid, as is each ring, and defines between them a gap or a width which is no greater than the diameter of the cable which may be wrapped about the arcuate hub flanges.

[0024] To shorten or lengthen a sign hanging cable to correct the height adjustment of a sign suspended from a ceiling or uppermost support location, the store employee would wrap or unwrap one or more turns of cable about the arcuate hub flange arrangement. The cable leading to a sign and to a ceiling support would include at least one wrap about the arcuate hub flanges, and that cable would be disposed (exit) tangentially with respect to those arcuate hub flanges. The cable would not by itself become unwrapped from the cable shortener apparatus by itself, because the width of the gap between the opposed rigid flanges of each opposed ring less than double the diameter of the cable. It would take manipulative effort by a store employee to pull one cable frictionally (squeezably) against its other end so as to unwrap or wrap the cable around the hub and thereby adjust the length of that sign hanging cable.

[0025] The invention thus comprises a cable shortener apparatus for permitting the length adjustment of a cable supporting a sign carrier from an overhead support, The cable has a certain constant diameter. The apparatus comprises a pair of rigid annular rings lockably engagable with one another, each ring having an inner arcuate hub flange which defines a hub surface for receiving at least one wrap of a support cable. An annular edge is arranged on each of the rings, and are spaced apart from one another when the rings are mated together, the spaced apart annular edges defining an annular gap no wider than the diameter of the cable. Each of the rigid annular rings has at least one arcuate locking flange for securing the rings to one another. The arcuate locking flange and the arcuate hub flange are radially adjacent one another.

[0026] Each of the annular rings may have at least two arcuate locking flanges, opposed to one another on an inner edge of each of the annular rings. Each of said annular rings may have at least two inner arcuate hub flanges, opposed to one another on an inner edge of each of the annular rings. The annular rings may have an annular inner wall which defines a cable wrap area with the inner hub flanges, about which the cable may be wrapped. The inner hub flanges on each of the rings may be spaced apart from one another by 90 degrees. The arcuate locking flanges on each of the rings may be spaced apart from one another by 90 degrees. It is to be noted that a different number of locking flanges and arcuate hub flanges than stated above, may be utilized on the rings to permit the mating of the rings and still accomplish the invention.

[0027] The invention also includes a method of adjusting a sign supporting cable holding a sign carrier from an overhead support, comprising the steps of mating together a pair of rigid annular rings, each of the rings having an arcuate hub portion, and a rigid annular edge defining an inner and an outer wall member of each of the rings, spacing the rigid annular edges apart by no more than the diameter of the cable, wrapping the cable about the hub portion of the annular rings to change the length of the cable supporting the sign carrier.

[0028] The method may include forming an arcuate inner locking flange on each of the rings to permit the rings to lock onto one another, rotating at least one of the rings about an axis of rotation so that the rings are out of phase with one another by at least 90 degrees when they are mated together, and spacing the inner locking flange on one of the rigid annular rings radially adjacent the arcuate hub flange of the other of the rigid annular rings when the rigid annular rings are mated together.

[0029] Thus, what has been shown as a unique sign cable shortener adjustment apparatus which permits a sign hanging cable to be readily, safely and inexpensively adjusted by a simple and inexpensive to manufacture and assemble sign cable adjustment apparatus in a very efficient manner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0041] Referring now to the drawings in detail, and particularly to FIGS. 1 and 1(a), there is shown the present invention which comprises a sign cable shortener apparatus 10 for hanging signs “S” and displays from an overhead support “O”, as shown in FIG. 1a, such support comprising a ceiling, beam or the like. A cable 12 having an upper end would be attached to a ceiling or overhead support “O”, and the lower end of the cable 12 would be attached to the sign to be supported from that ceiling or overhead support. One or more wraps of cable would be taken (or untaken) around the cable shortener as described hereinbelow, to shorten or lengthen that cable 12 as necessary.

[0042] The cable shortener apparatus 10 of the present invention as embodied in FIG. 1 thus comprises a rigid annular hub 14 having a pair of ends 16 and 18. A rigid annularly-shaped curvilinear flange 20 and 22 is disposed at each end 16 and 18 of the hub 14, as may be seen in FIG. 1. Each curvilinear flange 20 and 22 extends radially outwardly from the respective ends 16 and 18 of the hub 14. Each curvilinear flange 20 and 22 has a peripheral lip 24 and 26 respectively, which are also disposed radially outwardly of the hub 14. The curvilinear flanges 20 and 22 are spaced apart from one another on the hub 14 to define a cable wrap-space “M” between the flanges 20 and 22 and about the hub 14.

[0043] The rigid peripheral lip 24 of a curvilinear flange 20 on one end 16 of the hub 14 is spaced apart a certain distance “D” from the rigid peripheral lip 26 on the curvilinear flange 22 on the other end 18 of the hub 14. The certain spaced-apart distance “D” of the peripheral lips 24 and 26 is preferably greater than the diameter “X” of the cable 12 (line, drawn plastic filament or wire or the like) being utilized to support a sign “S” from the overhead support or ceiling “O”. The certain spaced-apart distance “D” of the peripheral lips 24 and 26 is critically less than the two cable diameters “X”, so as to prevent unintended wrapping (or more likely unwrapping) of the cable 12 past itself in the gap, that is, the certain spaced-apart distance “D” between the opposed peripheral lips 24 and 26 of the flanges 20 and 22. It would thus take a certain manual effort to squeezably move/slide the cable 12 past itself in the gap (“D”) between the peripheral lips 24 and 26 of the flanges 20 and 22 to unwrap and thus adjust the length of that cable 12 during its support of a sign. This effort would be easily accomplished by a store employee where such a sign were hung.

[0044] The cable shortener apparatus 10 may be readily adjusted, location wise on the extended cable 12 itself merely by sliding the shortener apparatus 10 one way or the other on that cable 12 or line, the cable or line being slid about the hub of the shortener apparatus 10 as the shortener apparatus 10 is being moved, with no winding of the cable/line 12 squeezingly past or over itself between the peripheral lips 24 and 26 being necessary.

[0045] Referring further to the drawings in detail, and again to FIG. 1a, et seq., there is shown a preferred construction embodiment of the present invention which comprises a sign cable shortener apparatus 10 for hanging signs and displays “S” from an overhead support such as a ceiling, beam “O” or the like by a cable, wire or line 12.

[0046] An embodiment of the shortener apparatus 10 construction is shown in FIG. 2 through FIG. 9(b) which comprises a first annular ring 114 and a second annular ring 116, as is shown best in FIG. 2, each ring 114 and 116 being identical to one another. The first (and second) annular ring 114 and 116 each comprises an annular housing 118 having a curved outermost wall 120 from a circular outermost edge 122 to a generally circular innermost edge 124.

[0047] Each ring 114 and 116 has an axis of rotation “R” which is perpendicular to the plane of the annular housing 118. Each ring 114 and 116 has a pair of arcuate locking flanges 126 extending axially away from the inner edge 124 of the curved side 120 of the annular housing 118. Each arcuate locking flange 126 is preferably an arcuate segment of about ninety degrees. Each arcuate locking flange 126 may be spaced apart from one another on the inner edge 124 of the housing 118 by about ninety degrees. Each arcuate locking flange 126 has an axial length “L” equal to the axial length of the opposed ring into which it will mate, as may be seen in FIGS. 2, 3 and 6.

[0048] Each annular ring 114 and 116 has arcuate hub flange 130 extending an axial distance “H” away from the curved wall 120 of the annular rings 114 and 116. Each annular hub flange 130 comprises an arcuate segment of preferably about ninety degrees, and has an outermost peripheral surface 132 which defines an outer hub or drum for winding receipt of a cable 112 thereabout. Each arcuate hub flange 130 on each ring 114 and 116 is disposed between adjacent arcuate locking flanges 126. Each adjacent locking flange 126 has a radially outermost peripheral surface 134 which is dimensioned and spaced so as to be received radially inwardly of each arcuate hub flange 130, as may be seen in FIGS. 2, 3 and 6.

[0049] In the assembly of a sign cable shortener apparatus 10, a first ring 114 is mated with a second ring 116, as may be seen in FIGS. 4, 5 and 6, each of those rings 114 and 116 being circumferentially out of phase with one another in this embodiment having only pairs of flanges, by about ninety degrees, so as to permit the radially outer peripheral surface 134 of the arcuate locking flange 126 of one ring (i.e. 114) to slide radially inwardly of the arcuate hub flange 130 of the other ring (i.e. 16) of the sign cable shortener apparatus 10.

[0050] When the two rings 114 and 116 are mated together, the inner curvilinear peripheral wall 138 of each ring and the circumferentially adjacent surfaces 132 of the arcuate hub flanges 130 defines a cable wrap area 140 in which a sign hanging cable 12 may be wrapped circumferentially therearound. The outermost peripheral lips or edges 122 of each ring 114 and 116 are rigid, as is each ring 114 and 16, and defines between them a gap or a width “D” which is critically less than twice the diameter “X” of the cable 12 which may be wrapped about the arcuate hub flanges 130. It is to be noted that the number of locking flanges and arcuate flanges may be changed according to design considerations, and is within the breadth of this invention.

[0051] In order to shorten or lengthen a sign hanging cable 12 to correct the height adjustment of a sign “S” suspended from a ceiling or uppermost support location “O”, the store employee would wrap or unwrap one or more turns of cable 12 about the contiguous arcuate hub flanges 130 arrangement. The cable 12 leading to a sign “S” and to a ceiling support “O” would include at least one wrap of cable 12 about the arcuate hub flanges 130, and that cable 12 would be disposed (exit) tangentially with respect to those arcuate hub flanges 130, as may be seen in FIG. 4. The cable 12 would not become unwrapped from the cable shortener apparatus 10 by itself, because the width “D” of the gap between the opposed rigid flanges or edges 22 of each opposed ring 114 and 116 is to be less than twice the diameter of the cable 12. It would take manipulative effort by a store employee to pull one cable 12 frictionally against its other end so as to unwrap or wrap the cable 12 around the hub and thereby adjust the length of that sign hanging cable.

[0052] A further embodiment of the construction and assembly of the cable shortener 10 of the present invention is shown in FIG. 7(a) wherein a first ring 150 having a first annular peripheral lip 152, a short drum 154 of short axial length, and a second ring 156 having an annular peripheral lip 158 are shown in an exploded depiction. The drum 154 and the first and second rings 150 and 156 are mated together in a male-female relationship to form a rigid cable shortener 10 in this embodiment by a press fit, or by a bonding of radially adjacent annular surfaces 160 and 162 to define the cable shortener 10 similar to that shown in FIG. 1, which when assembled in this particular embodiment, is shown in perspective view in FIG. 7(b) with the larger annular cable wrap receiving chamber and a narrow gap between the peripheral lips 152 and 158 of a dimension which is less than twice the diameter of a cable/line to be wrapped about the drum 154, to deny easy overlap and undesired unwinding of a cable from the cable shortener.

[0053]FIG. 8(a) another assembly embodiment of the cable shortener ring 10, wherein a first ring 170 and a second ring 172 each have an inner peripheral lip 174 are presented in an exploded perspective view. Each ring 170 and 172 has a pair of arc segments 176 and 178 extending in one axial direction from that peripheral lip 174, as well as an arcuate gap 180 between peripherally adjacent arc segments 176 and 178. To construct a cable shortener 10 in this embodiment, the rings 170 and 172 are arranged in a lip-to-lip orientation with the rings 170 and 172 in an exemplary 90 degrees out of phase with one another so that an arcuate segment 174 of one ring 170 or 172 mates with an arcuate gap 176 or 178 of its mating ring 172 or 170. Such a mating of gaps 176 and 178 and segments 174 may then be sonic welded or bonded at their respective touching surfaces to form the rigid cable shortener 182 which is similar to the cable shortener 10 shown in FIG. 1.

[0054]FIG. 9(a) shows yet a further embodiment of the construction process of the cable shortener 10 of the present invention. An annular generally U-shaped channel 190 is molded or formed of a plastic material as a generally torroidal shape with an open outermost peripheral gap 192 defined by a pair of radially outwardly directed walls 194. After such molding operation, the outermost peripheral lips 196 of the walls 194 may be heat and/or pressure formed toward on another to create the narrow rigidly spaced apart relationship of those outermost peripheral lips 196, a distance apart as recited in the aforementioned embodiments, of less than twice the diameter of a cable wrapped about the hub or channel of the cable shortener, the assembled construction in this embodiment being shown in FIG. 9(b).

[0055] Thus, what has been shown as a unique sign cable shortener adjustment apparatus which permits a sign hanging cable to be readily, safely and inexpensively adjusted by a simple and inexpensive to manufacture and assemble sign cable adjustment apparatus in a very efficient manner. The cable shortener being shown as constructable by several techniques which permit the unique annular cable wrap receiving torroid with a narrow peripheral cable entry/unwind gap between adjacent lips thus facilitating the adjustment of the length of a sign hanging cable. The cable or line of the present invention is preferably made of a strand(s) of plastic, metal or cotton-like construction (and may be about for example about n one thirty-second of an inch or so in diameter, although larger or smaller diameters are within the scope of this invention).
